We report here a simple solution combustion synthesis of Nickel oxide (NiO) nanoparticles by using glycine as a fuel and nickel nitrate hexahydrate (Ni(NO3)2.6H2O) as an oxidizer and it’s reduction to nickel nanoparticles by using hyderogen gas. The morphological structural properties of nanoparticles were investigated by scanning electron microscopy (SEM), Xray diffraction (XRD), Fourier transform infrared (FT-IR) and UV-Visible spectroscopic technique. The solution combustion-synthesized Ni nanoparticles have a crystalline size of ~ 20 nm. The agglomeration of fine particles with particle size in the range of 30~50 nm is seen by SEM images. The FT-IR spectrum shows absorption band at ~ 466 cm-1 for Ni nanoparticles. UV-Vis. Spectroscopy shows absorption band for NiO at ~ 350 nm and Ni at 400 nm. Ni nanoparticles are used in different fields like CNT synthesis catalysis supercpacitors etc.
